Question

我正在使用CodeIgniter，使用Bootstrap构建一个网站，该网站有一个联系页面。

我无法对PHP / Form Helper构建的文本字段进行样式化，因为我不确定在哪里使用标记，我尝试的每个解决方案都会产生额外的文本字段，或者只是插件出现，或者什么都没有。

控制器：

    <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Welcome extends CI_Controller {

    /**
     * Index Page for this controller.
     *
     * Maps to the following URL
     *      http://example.com/index.php/welcome
     *  - or -  
     *      http://example.com/index.php/welcome/index
     *  - or -
     * Since this controller is set as the default controller in 
     * config/routes.php, it's displayed at http://example.com/
     *
     * So any other public methods not prefixed with an underscore will
     * map to /index.php/welcome/<method_name>
     * @see http://codeigniter.com/user_guide/general/urls.html
     */

    protected   $sendEmailTo    =   'you@you.com'
    protected   $subjectLine    =   ""; // actually set on line 39.

    // views
    protected   $formView       =   'contact';
    protected   $successView    =   'contact_success';
    protected   $headerView     =   ''; //null to disable
    protected   $footerView     =   ''; //null to disable

    // other
    public      $data           =   array(); // used for the views


        public function contact()
    {

        $this->load->library('form_validation');
        $this->load->helper('url');
        $this->subjectLine = "Contact form response from " . $_SERVER['HTTP_HOST'];
        $this->form_validation->set_rules('name', 'Your name', 'trim|required');
        $this->form_validation->set_rules('email', 'Your Email', 'trim|required|valid_email');
        $this->form_validation->set_rules('message', 'Message', 'trim|required|xss_clean');

        if($this->form_validation->run() == FALSE) {
            // show the form

            if ($this->headerView) { $this->load->view($this->headerView,$this->data); }
            $this->load->view($this->formView,$this->data);
            if ($this->footerView) { $this->load->view($this->footerView,$this->data); }

        } else {
            // success! email it, assume it sent, then show contact success view.

            $this->load->library('email');
            $this->email->from($this->input->post('email'), $this->input->post('name'));
            $this->email->to($this->sendEmailTo);
            $this->email->subject($this->subjectLine);
            $this->email->message($this->input->post('message'));
            $this->email->send();

            if ($this->headerView) { $this->load->view($this->headerView,$this->data); }
            $this->load->view($this->successView,$this->data);
            if ($this->footerView) { $this->load->view($this->footerView,$this->data); }


    }

        </tr>";

?>
</table>

<?
    echo form_close();
?>
</div>

我想使用的示例Bootstrap CSS：

<div class="input-group">
  <span class="input-group-addon">@</span>
  <input type="text" class="form-control" placeholder="Username">
</div>

Answer 1

首先，您应该在php标记之外构建标记，并使用php来回显各个输入，您可以将所需的属性作为数组参数传递给form_input()，有关here的更多信息。

示例：

<div class="input-group">
  <span class="input-group-addon">@</span>
  <?php echo form_input(array("class"=>"form-control","placeholder"=>"Username"))?>
</div>

关于表单的codeigniter + bootstrap的一个很棒的事情是，一旦你设置了一些配置默认值，你就不必考虑它。做一些配置来保存引导代码并使用codeigniter表单帮助器为表单字段所需的代码创建数组。那样重要的一切都发生在配置文件中，视图非常简单。

 // in config file -- this is bootstrap code that is repeated over and over 
 // so i just make some quick configs to hold the html code
 $config['btcgroup'] = '<div class="control-group">';
 $config['btclabel'] = array(
'class' => 'control-label'
 );
 $config['c2divs'] = '</div></div>';

// quick form field example
$config['spnam01'] = 'Shipping First Name';
$config['spary01'] = array(
'name'        => 'sp01',
'maxlength'   => '60',
'size'        => '20',
'class' => 'input-medium',
'placeholder'=> 'First name'
);
$config['sphelp01'] = '<p class="help-block"> Required Field </p>';

 // and put it together in the view for form field sp01
    echo $btcgroup.form_label($spnam01.$formreq, 'sp01',$btclabel ).$btcontrols.form_input($spary01,set_value('sp01')).form_error('sp01'); 
echo $c2divs;

没有构建表单的HTML代码。 我们不会尝试混合php和html 一旦你有了你喜欢的模板 - 你可以非常快速地创建表单。（请注意，此示例中可能缺少某些内容，但它应该让您入门）

使用PHP，CSS，CodeIgniter和Bootstrap联系表单
